IIS Belleville Washers are manufactured in Imperial as well as Metric sizes. Belleville Washers, also called Conical Spring Washers are manufactured as per DIN 6796 and DIN 6908 Standards. IIS Belleville Washers are designed specifically for Heavy Duty Bolted Section such as Bus Bars, Transformers, Rectifiers, Heat Exchangers, Transmissions etc. These washers are intended to counteract the effect of setting which results in bolt/nut assemblies working loose. They effectively prevent loosening of the assembly under varying radial load and are designed for use with short bolts predominantly subject to thrust. Belleville Washers are high stressed components and cannot be used for Dynamic Loading and Infrequent Varying Load Applications.
IIS has ready Stock of all Standard Sizes of Belleville Washers in High Carbon Steel, Stainless Steel 300 series, Inconel®, 17-7 PH etc. with a variety of surface finishes.

Belleville washers
LockRite Washers deliver maximum joint security under extreme vibrations and Dynamic Loads. LockRite Washers are used along with bolts and offer resistance to self loosening behaviour during vibration and fluctuating loads. The Inner Wedges of LockRite Washers lock themselves with each other and Outer Serrations get locked on the respective mating surfaces leading to a secure Bolted Joint. Using LockRite Washers reduces self loosening of bolts.
LockRite Washers are available in Alloy Steel coated with GEOMET® 720, Stainless Steel (Surface Hardened) 316L, Inconel 718 and Duplex.
LockRite Washers are 100% manufactured and tested in India. We produce LockRite Washer to fit standard bolts sizes as well as with enlarged outer diameter used for flanged bolts. Custom Sizes available on request.

IIS Serrated Washers are Coned Washers with Trapezoidal Ribs across the cross section on both sides for gripping. IIS Serrated Safety Washers are ready to fit washers to sustain preload and avoid loosening. As the bolt is tightened the serrations crunch into the mating surfaces and prevent the screw from loosening due to vibration. Also the disc shape holds the necessary pre-tension. They are available in various sizes to fit bolts or screws. The diameters for Serrated Washers are matched to screw dimensions. The outer diameter of washer is matched to the diameter of screw head. This allows using screw and bolt including recessed heads, except countersunk screw.
The advantages of IIS Serrated Safety Washers are: 1. Used for high vibration resistance due to positive rib contact 2. Excellent pre-tensioning3. No splitting/cracking occurs during tightening4. The concentric force of the washer eliminates the chances of bending fasteners

IIS manufactures Ball Bearing Disc Springs (Plain and Slotted) used in maintaining positioning accuracy of bearings with no end play. Ball-Bearing Disc Springs are used with radial Ball bearings to minimize vibration and shaft deflection. Proper preloading will increase bearing rigidity and eliminate excessive wear and tear and running noise. Application of Preloaded Bearing Washers in Electric Motors helps to reduce operating noise. The preload force remains practically constant even when there is axial displacement of the bearing as a result of thermal expansion. The recommended preload is achieved when the Disc Springs are deflected to 75% of the free height.
Slotted Disc Springs have relatively low forces and are used with small size ball bearings. Disc Spring with slots have a strong digressive characteristic which helps in constant spring force over a large deflection range. We are able to achieve flatness through our special heat treatment process and full contact area helps in uniform preload.
Advantages of Ball Bearing Disc Springs (Preloading Washers):
1. The Spring load remains nearly constant for a large deflection range
2. Backlash Compensation & Regressive Curves help reduce preload variations
3. Very low force characteristics with very large deflection range
4. Multiplication of force by stacking of two or more in parallel
5. Available in sizes to accommodate all Bearing Sizes
6. Round shape ensures equal distribution of load around the bearing ring
